Anyway, back to "what would I use OS4 for", which was the guys question after finding that Amiga browsers aren't all that up-to-date (although I still use IBrowse heavily), I use OS4 for:
Programming (GCC)
Browsing (IBrowse)
E-Mail (Simplemail)
Playing music (TuneNet will all its plugins)
Watching video files (MPlayer, DvPlayer)
Making music (Hivelytracker)
FTP (PFTP)
IRC (AmIRC)
Instant Messaging (Jabberwocky)
Graphics (Photogenics, Personal Paint)
Emulation (VICE, MAME)
A lot of the software I use is available in native OS4 PPC versions. There is an archive of OS4 software available here:
http://www.os4depot.netBack to the browser question, I use IBrowse a lot, but also someone has built firefox for OS4, but it doesn't quite work yet.
Also, the author of Sputnik (a browser for MorphOS) should receive an OS4 machine any day now and there is a pot of cash waiting for him if he ports it to OS4.
So, the situation may improve.
